FLOOR-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 779,773, dated January 10, 1905.

' Application filed September 23, 1903. Serial No: 174,324.

To all whom it may concern:

Be it known that we, WILLIAM A. DUNAWAY and PETER H. MELANDER, citizens of theUnited States, residing in Tacoma, in the county of Pierce and State of X/Vashington, have in vented certain new and useful Improvements in Floor-Sweepers, of which the following is a specification.

Our invention relates to devices for sweeping dust from floors, and has for its objects to simplify the construction and increase the efficiency of such machines. WVe attain these objects by the devices illustrated in the accompanying drawings, in'which- Figure 1 is a vertical longitudinal section of our machine. Fig. 2 is a plan thereof, the cover and dust-pans being removed to show the interior. Fig. 3 is a plan of the spongewheel. Fig. 4 is a plan of the brush-wheel. Fig. 5 is an enlarged section of the air-fan. Figs. 6 and 7 are details of the sponge-wheel and brush-wheel, respectively; and Fig. 8 is a plan of the main axle.

Similar letters of reference refer to similar parts throughout the several views.

Our machine is contained in a casing A, having four vertical sides, a closed top, and open bottom, and supported on a pair of wheels B on the central axle C and on the central casters D at the two ends of the casing A. The machine is pushed by means of a handle E, pivoted to each side of the casingA at a point in line with the axis of the hereinafter-described fan. The handle may be swung on these pivots, so that either end of the machine may be the front. I

Across one end of our machine is the rotary .brush, formed of two parts F, which are removably mounted on the shaft G, to which the central pulley H is secured. These parts F are provided with four or more longitudinal recesses I, shaped substantially as shown in Fig. 7, into which the brush-holders J may be slid. These brush-holders J fit the grooves or recesses I and may be removed therefrom in order to renew the bristles K, which are secured therein. We prefer to make the bristles K of fine material, such as camels hair. Across the other end of the machine is a rotary mop, formed similarly to the rotary 5 brush of two parts L, removably mounted on shaft M, having a central pulley N secured thereto. Within the recesses O in the parts L is slid the holder P, having sponges Q, se-

cured therein. 5 5

The above-described central axle C is shown in Fig. 8 and is provided at its center with the double-grooved pulley B. This pulley drives the pulleys H and N by means of the belts S, which we cross, so as to cause them to rotate in the opposite direction to the wheels B. The grooved pulley T is also mounted on the axle C and is adapted to drive the hereinafter-described fan.

The brush and mop operate within fines or 5 passages U, leading upward and converging toward the center of the machine. These passages U connect with the cylindrical box V, from which the two dust-spouts W lead, connecting with the dust-pans WV. box V- is the rotary fan X, mounted on the shaft X and driven by a belt from the pulley T. This fan X sucks the air from the passages U and sends it through one of the spouts W. The spouts IV are provided with a cutoff plate Y, controlled by the handle E by means of the rod Z and so shaped that whichever position the handle E may be in the spout W pointing forward is open and the rearward one is closed, as is shown in Figs. 1 and 5. 30 The dustpans W are made removable, as shown.

What we claim, and desire to secure by Let ters Patent, is

1. In a floor-sweeper, the combination of a 5 casing, an axle centrally mounted in said casing, supporting-wheels on said axle, a rotary brush driven from said axle and located near one end of said casing, a rotary mop driven from said axle and located near the other end 9 of said casing, a rotary fan driven from said axle and located above it, dust-fines leading from said brush and mop to said fan, and a dust-pan adapted to receive the dust from said fan.

2. In a floor-sweeper, the combination of a Within the 7 casing, an axle centrally mounted in said casing, supporting-wheels on said axle, a rotary brush driven from said axle and located near one end of said casing, a rotary mop driven from said axle and located near the other end of said casing, a rotary fan driven from said axle and located above it, dust-fines leading from said brush and mop to said fan, dust.- spouts connecting With said fan, a movable IO plate adapted to close one of said dust-spouts and to open the other, and means for operating and controlling said plate.

In testimony whereof We have signed our names to this specification in the presence of two subscribing Witnesses.
